摘要： A channel for a data processing system is provided with a time of day clock that is synchronized with the time of day clock of the associated central processor. Both the central processor and the channel processor record times of particular events, and the channel uses these times to calculate two times called Function Pending and Function Active. Both times begin when the central processor executes an instruction to begin an I/O operation. Function Pending ends when the channel has made successful initial selection. This time shows delays by the channel processor in scheduling the channel control unit, and device resources for I/O operations. Function Active ends at Channel End. A new instruction, Set Channel Monitor, enables or disables these measurements. An information block for each subchannel defines one of several measurement modes for a subchannel or disables the subchannel from measurement.

摘要： Multiprocessing systems having changeable CPU configurations generate unique changeable identifications (ID's). These are presented by I/O channels over various I/O connection paths, in association with special path defining commands and function data. Related path state indications are stored peripherally in path map tables and define path group associations for sustaining path-independent I/O operations. When a device is reserved via one path in a path group the reserve affiliation is extended automatically (in the path tables ) to each path in the group, thereby rendering each path accessible in a reserved mode. The path defining commands are used for adding paths to, resigning paths from and disbanding groups. Special sensing commands are used for sensing path reservation and grouping states. When a command for adding or resigning a path is presented to a reserved device via one path in a group the reserve is automatically realigned to the enlarged or reduced group. When a command for disbanding a group is presented to a reserved device the reserve is realigned to apply only to the path on which the command is presented. The foregoing special commands are required to be obeyed by the device even if it currently has a conflicting allegiance to the same system or another system. Consequently, paths can be added to an established path group without requiring potentially premature release of any allegiance.
摘要翻译：具有可更改CPU配置的多处理系统可生成唯一可更改的标识（ID）。这些通过各种I / O连接路径的I / O通道与特殊路径定义命令和功能数据相关联。相关路径状态指示外围存储在路径映射表中，并定义用于维持与路径无关的I / O操作的路径组关联。当通过路径组中的一个路径保留设备时，保留联盟将自动扩展（在路径表中）到组中的每个路径，从而使每个路径在保留模式下可访问。路径定义命令用于添加路径，撤销和解散组的路径。特殊传感命令用于感测路径预留和分组状态。当通过组中的一个路径将添加或重新命名路径的命令呈现给保留设备时，保留将自动重新对准放大或缩小的组。当将分组解除组的命令呈现给保留设备时，保留被重新对齐以仅应用于显示命令的路径。上述特殊命令需要被设备遵守，即使它当前对相同的系统或其他系统具有冲突的效忠。因此，可以将路径添加到已建立的路径组中，而不需要潜在地过早释放任何效忠。

摘要： A new instruction called Test Subchannel assures that one processor will not begin an I/O operation with device status information that has been outdated by an operation of another processor. When a device has status to present, a status pending bit and an interruption pending bit are set in the channel subsystem and an interruption request is made. When a processor accepts an interruption, the channel system resets the interruption pending bit but not the status pending bit. The processor that accepts the interruption updates the unit control block (UCB) in main store and resets the status pending bit in the subchannel unless the UCB has been locked by another processor that is starting an I/O operation on the same device. This invention prevents the other processor from operating with outdated status information in the UCB. A processor that has locked the UCB uses Test Subchannel to test the Status Pending bit in the subchannel. If status is pending, the processor executes a routine to update the UCB. Optionally, when a processor that is handling an interruption finds the UCB locked, it sets a flag bit in the UCB lock word. Before a processor resets the UCB lock, it checks the lock word and executes the Test Subchannel instruction if the flag is set.
摘要翻译：称为测试子通道的新指令确保一个处理器将不会开始I / O操作，其中设备状态信息已被其他处理器的操作过时。当设备具有呈现状态时，在通道子系统中设置状态待决位和中断等待位，并进行中断请求。当处理器接受中断时，通道系统将复位中断等待位，但不复位状态未决位。接受中断的处理器更新主存储器中的单元控制块（UCB），并重置子通道中的状态未决位，除非UCB已被同一设备上启动I / O操作的另一个处理器锁定。本发明防止其他处理器在UCB中使用过时的状态信息进行操作。锁定UCB的处理器使用测试子通道来测试子通道中的状态待决位。如果状态为待处理，则处理器执行例程来更新UCB。可选地，当处理中断的处理器找到UCB锁定时，它在UCB锁定字中设置标志位。在处理器复位UCB锁之前，如果设置了该标志，它将检查锁定字并执行测试子通道指令。

摘要： Program instruction TPI (Test Pending Interruption) and associated data processor sequence controls for its execution enable interruption handling programs to operate in a shortened recursive mode relative to interruptions pending while such programs are in control of a data processor system. Execution of a TPI instruction sets a condition code distinguishing between pendency and non-pendency of a request for interruption in one associated class of interruptions. If an interruption request in that class is pending, the instruction execution controls clear (terminate) it. If more than one request is pending, a selected one is cleared. The selection is based on a predetermined priority ordering. Interruption code information is stored by the execution controls, indicating the source of the cleared request. The interruption handling program branches on the condition code and the interruption code information, to attend to the interruption task associated with the cleared request. Since that program is in control of the system when the TPI instruction is executed, the branch sequence may omit status saving operations and other operations associated with the handling of interruptions.
摘要翻译：程序指令TPI（待定中断测试）和相关数据处理器序列控制用于其执行使得中断处理程序能够以缩短的递归模式运行，相对于此类程序控制数据处理器系统期间的待处理中断。 TPI指令的执行设置一个条件码，区分一个相关联的中断类别中的中断请求的未决和非倾向。如果该类的中断请求处于待处理状态，则指令执行将清除（终止）它。如果多个请求处于待处理状态，则选中的一个请求将被清除。该选择基于预定的优先顺序。中断代码信息由执行控件存储，指示已清除请求的来源。中断处理程序分支条件代码和中断代码信息，以参加与清除的请求相关联的中断任务。由于该程序在执行TPI指令时控制系统，所以分支序列可以省略与处理中断有关的状态保存操作和其他操作。

摘要： Enables an I/O channel program to use IDAWs (indirect data address words) to control data transfers from/to an I/O (input/output) device to/from either or both of ES (expanded storage) and/or system MS (main storage), in which data moved to/from ES does not move through MS. ES and MS are plural electronic storage media in a data processing system, and the I/O device is any I/O device selectable by the system. Intermixing of data transfers between ES and MS may be controlled by a single IDAW list accessed by a channel control word (CCW) in a channel program in a data transfer direction indicated in the CCW without any channel mode change.

摘要： A method, apparatus and program product for the non-disruptive recovery of a single partition in a multipartitioned data processing system. A server contains multiple partitions connected to a single channel adapter which is used to send data and commands to a fabric. A request is sent by the adapter to the well-known address for the fabric. The request includes an identification of the port associated with the partition to be removed. Upon receipt of the request, the fabric removes all resources associated with the port being logged out without affecting ongoing operations in other partitions.

摘要： The present invention provides for a method of transferring information in a network computing system environment. The network environment includes a main storage coupled to a channel subsystem with a plurality of channels in processing communication with a control unit capable of coupling to a plurality of input/output devices. First packets of data are concurrently sent to and from the main storage. The operation of certain channel functions are also transferred to the control unit so that each command does not require a command response or an end notification response. Finally by certain commands are combined with the associated data of one or more of the data packets. In one embodiment of the present invention, an optical fabric is also in processing communication with said channels and control unit.
